Genshin Impact
Jadeplume Terrorshroom, strategies, weak points, and achievements
Defeat the giant Dendro Chicken, which changes its behavior depending on which elements you use on it.

The Jadeplume Terrorshroom is a Boss introduced along with the Sumeru region, and just like most Fungi, it will have special interactions whenever you use Pyro or Electro on it; defeating it will reward you with Majestic Hooked Beaks and Dendro Elemental Gems.

Jadeplume Terrorshroom

Strategy
The Jadeplume Terrorshroom is only highly resistant to Dendro Damage and will act differently if hit by Pyro or Electro, so plan accordingly which elements you want to bring.
During its normal phase, this Boss will have three different attacks: short-range with its beak, mid-range with a Dendro explosion, and long-range by firing Spores at you.
Electro Damage and Electro+Dendro Reactions will feed its rage meter; when full, it will become "Activated," making it stronger and more aggressive, but it becomes tired after a full attack and stays on the ground weakened for about 10-15 seconds.
The Burning reaction (Pyro+Dendro) will make it "Scorched," slowing it and generating some spores that will become Fungi if not destroyed. The Jadeplume Terrorshroom will return to normal after this.
Weak Point
The Jadeplume Terrorshroom will receive extra damage when hit on the head.
When this Boss is tired on the floor after the "Activated" phase, it will be even weaker to most kinds of damage, though it is still resistant to Dendro.
Achievements
Three Strikes
Witness the three powerful abilities used by the activated Jadeplume Terrorshroom.
These are a stronger beak attack, a stronger long-range spore attack, and one where it charges at you; you don't have to see all three attacks in the same fight; all you need to do is witness them happening; it will happen eventually if you keep activating it.
I Can't Take It Anymore!
Defeat an exhausted Jadeplume Terrorshroom after its activation state is finished.
Defeat the Boss before it gets up after the Activated phase, so you better do a lot of damage in under 15 seconds or weaken it before activating this phase.
The Smell of Grilled Mushrooms in the Morning
In a single challenge, defeat 6 Fungi produced by Jadeplume Terrorshroom in a Burning state.
Burn the Boss at least twice so it summons the spores; there can only be four at a time, so defeat at least two before burning the Boss again.
Nanomachines, Son!
Defeat an activated Jadeplume Terrorshroom while it is unleashing a powerful skill...
When Activated, it will perform only one attack, so you must defeat it quickly while it is attacking.
